especially to a hangerthat may bey coriveniently used with the standard M. .'C. B.

' brake' head.

Iao

It ,fis well known that after a brake beam has y'been in use for some length of time. unless some additional support isused` it is apt to tilt, eausingia great unevenness` of wear vof the brake s oe. in fact it often hap-l pens that the upper end of the brake shoe will be entirely worn away while the lower half will only be partly worn. The shoe will then have to be scrapped and a new oney supplied,swhieh of course means thatV the shoe 'has only given half of the service for which it is designed.

Also it often, happens that the brake beam will drop if the shoe and key become lost allowing the head to slip from the brake hanger, which is the cause of a great number of derailments. y

An object of my invention therefore is to provide a hanger of novel construction that will tend to hold the head in place even though the brake shoe and key should become lost in service, and by holding the head php brake beam will of course likewise be Still another object of my invention is to provide a hanger that will be accommodated by the standard M. C. B. brake head so that no additional work on the brake head is necessary when" applying my hanger.

Still another object of my'invention is to provide a hanger wherein the auxiliary arm is normally at rest but will come into operation when the brakes are applied and form a truss-like hanger, or support.

Still another object of my inventionl is to arrange the auxiliary arm so that when in its inoperative position it will still be an additional means for preventing the brake beam and head from falling.

With these and other objects in view my invention consists in certain new andnovel constructions and combination of parts as will be hereinafter fully desoribed and pointed out in the claims.

mentioned.,

In the drawings:

Figure l is a side elevation of a standard M. C. B. head supported by my improved hanger, the head and shoe fbeingi'n' their normal position;

Fig. 2 is a similar view but the same being moved to the position they occupy when y the brakes are applied; and

Fig. 3 is a front elevation of the improved hanger.

Referring now to the drawings, a standard M. C. B. head l is shown, which has thetwo openings :2 and 3 therein, and as far as Iam aware only one of these openings have heretofore been used forlthereception of the brake hanger at the one time. Some of the roads use short hangers to be placed in the opening 3, while others use longer hangers and use the opening 2. f

My invention 'however contemplatesl the use of both openings at the`one time, andl therefore provide vtwo hanger' members 4 and 5. rlhe hanger member: is substantia/lly U-shaped, being slightly offset or. bent near its lower end as at 6, so that it will allow the other hanger member 5 to freely operate in the opening 3.' This hanger member 4 normally supports the beam and head, as it will be seen ,from/Fig. l, that the length of the other hanger member 5 is such that when the head isf'in the position shown the lower arm 7 of the hanger membenp is not in contact with the upper wall ofthe opening 3, but simply swings or idles in the opening. but of course will tend to keep the head from dropping down should the shoe S and key 9 be lost or otherwise removed.

Another advantage of a hanger of this kind is that when the brakes are applied and the kbeam '10 moved forward forcing the head slightly upward, the shorter hanger member 5 will come into operation and vmove slightly outwardly from the hanger member 4, as clearly showny in Fig. Q. The

llower arm 7 will tightly lit against the upper wall of the opening 3, forminga twopointisupport for the head and the third point of support is by the pin 11 that passes through the eyes in the upper ends of both the hangermembers 4 and 5, which pin 11v is supported in a bracket 12, the bracket forming no part of the present invention.

rlhis short hanger member 5 of course pre- .vents the upper end of the head from tilting forwardly, which tilting is the cause of the unevenness of weer of the shoe as before rIhis shorter hanger member 5 is also substantially U-shaped, the side arms 13, however, being bent inwardly as at 14 and then again upwardly as at 15 to be supported by the pin 11, the upper end thereof being slightly offset. By bending these arms 14: inwardly the brake head 1 will have to be tilted slightly before the same can be removed, so that this shorter hanger 5 also prevents the accidental loss of the brake head. d

Any form of -pin 11 may be used, and in the present instance I have shown one that is provided with a slot through which is passed a cotter pin 16 to prevent the loss of the said pin 11 from the bracket 12.

From the foregoing it will be seen that I have devised a brake hanger that is comparatively' simple t0 construct, consisting of but two hanger members of certain shape and length and a pin for pivotally supporting the same. Furthermore, the hanger may be used with any M. C. B. standard head or head that is provided with the two openings 2 and 3, and with my hanger it is not necessary to construct or form any special form of brake head. Furthermore, the shorter hanger prevents the objectional tilting of the upper end of the brake head and assistsin supporting the brake head and beam when the brakes are applied andthe head moved forwardly. It also prevents the accidental d loss of the brake head, vand if for any reason .the larger hanger member 4 should become broken or damaged, the shorter arm 5 will still support the head and beam and prevent the dropping of the same. f

I am aware that speci heads have been constructed with two supporting means and I do not claim such, but what I do claim and desire to secure by Letters Patentis:

1. In combination with a brake head having two openings for the reception of a brake hanger, a brake hanger comprising two hanger members one fitting within each of said openings, one of said hanger members being idle when the head is in its normal position and assisting in supporting the head when the said head is moved forwardly.

2. In combination with a brake head having two hanger openings, a long hanger lmember in one of said openings and supporting the head at all times, and a shorter hanger member loosely fitting within the other of said openings and supporting the head only when said hea'd is moved in a forward direction.

3. In combination with a brake head having two recesses therein for the reception of al forms of brake one in each of said openings, one of said hanger members supporting the head at all times and the other preventing the upper portion of the head from tilting forwardly.

4. In combination with a brake head having two openings for the reception of a brake hanger, two hanger members of different lengths pivoted from the same center and extending into said openings, the hanger of shorter length idling in said opening until the brake head is moved in a forward direction and then forming a truss arrangement with the other hanger to support the said bra-ke head.

In combination with a. brake head having two hanger openings, two hanger members of different lengths pivoted from the same ycenter and extending into said openings, the hanger of shorter length idling in said opening until the brake head is moved forward and then assisting in the support of said head. said shorter hanger preventing the upper end of the brake head from tilting forwardly and arranged to prevent the brake heaid yfrom being movedv rearwardly off said hanger without first tilting the same upwardly.

6. A brake hanger comprising a substantially U-shaped hanger member, a second' hanger member being shorter in length than the first mentioned hanger and means for supporting both of the said hanger meinbers alongone central axis.

T. A brake hanger comprising a substantially U-shaped hanger member, said member being slightly offset near its lower end, a second hanger member also substantially- U-shaped, and a pin supporting both of said hangers alongthe one central axis.

8. A brake hanger comprising a substan-V tially U-shaped hanger member and a second hanger member also substantially U- shaped but having its upper arms bent inwardly and then upwardly, and a pin passing through both of said hanger members for supporting the sa-me.

9. A brake lhanger comprising a substantially U-shaped hanger member said member being slightly offset near its lower end, a second hanger member being shorter in length than the first mentioned hanger member and having its upper arms bent inwardly and upwardlyv and the ends of said armsbeing slightly offset, and a pin passing through the upper ends of both of said hanger members. l

In testimony whereof I affix my signature.
